crashpc: As usual, with basic JPEG processing, grass looks like ugly mush. ISO performance is okay, but I still wonder If I shouldn´t jump to FF... Decisions, Decisions!

with canon cameras .. DLO really helps foliage, but any bayer array camera will look mushy.

I got spoiled with the sigmas where foliage and grass just looks incredible.

Snow pics look great Barney. I really liked 28/29 .. especially down here where I have to turn on the AC still :p

On article Gear of the Year: Carey's choice - Canon PowerShot G9 X (173 comments in total)

I've been going back and forth over this camera for the longest of times for the same reason - it's simply a take anywhere camera that's so freaking small with a half decent sensor size.

Of course I wonder when the G9XII is coming out with the performance improvements of the G7X II.. so i'll probably wait a little longer.

On article Lensrentals tears down the Nikon 105mm F1.4 (152 comments in total)
In reply to:

Favorable Exponynt: So there are gears. They implied it was a ring type, so they lied. Gears can break. Especially plastic ones. Somebody should have them examined to determine whether the lens has a built in technical life span.

actually the point of ring USM is there's no real "motor" to drive the lens.

Micro motor / Motor USM which canon uses on their smaller and cheaper lenses, uses a USM motor to drive gears similar to this lens. but a ring type USM? no motor. two rings, one as a stator that has a high frequency AC applied to it to move the other ring.

the SWM part was a bit eyeopening or .. eyebrow raising.

micro motor USM wasn't really what you'd think that Nikon was describing.

ah wait, Apple invented curved sensors in 2016
https://www.dpreview.com/articles/8027168176/apple-patent-describes-use-of-curved-image-sensor-to-design-small-camera-module
and we all know that Apple really invented everything. or did they?
http://digitalsynopsis.com/buzz/did-apple-actually-invent-anything-infographic/

except if you looked at this patent closely. you'd realize it was taking the curved sensor approach and attempting to reduce the thickness of the sensor by not curving all of it.

In reply to:

HowaboutRAW: Or take the Leica-Kodak and Ricoh approach and curve the microlens array.

Yeah, sure in 30 years, single atom micro manufacturing may be able to make a sensor that has manmade rods and cones (like human eyes) and they could be built on a curved plane, but that type of sensor is likely to be made of significantly different materials than sensors of 2016. Then such technology will cost tens of billions of dollars to develop.

they have patents in both areas. however with that, there's still potential issues, it's not infallible.

In reply to:

entoman: I'd be very surpised if this made its way into interchangeable lens cameras, as it would entail creating a whole new set of lenses to match the curved sensor. It's very much easier to correct vignetting in software.

These sensors are more likely to be used in a fixed lens device such as a cheap compact or a mobile phone.

I could see these being used on large sensor compacts. the sensor curvature, lens design would then go hand and hand.

On article Mobile Speed: Portable SSDs for photographers (200 comments in total)
In reply to:

rrccad: the only issue with SSD's for this type of usage, is that you are re-writing data alot.

the age of the SSD is entirely determined by the number of bytes written to it, and the write error rate and once it reaches a point of no return, the controller will first stop writes to the SSD, and then the next subsequent reboot - most will entirely brick the SSD. no reads, no writes.

RAID for most controllers doesn't buy you anything, since the number of bytes written would be the same, and *usually* both drives would fail at around the *same* time especially if they were made from the same batch.

SSD's are great for speed - however there is certainly much more caveats when it comes to continual changing data as a dump, backup,etc device.

you also have more potential issues with disconnection of the drive from the computer than you would with a spinning hard drive especially as the SSD gets older as the wear leveling takes more time post write.

for backups? not really. and most consumer spindle drives don't have the same limitations as do SSD's.

for them it's oxidization, humidity and operational aspects that can more of an impact on longevity.

the thing is.. if the review is going on about how rosy SSD's are, some caveats should be mentioned. they are not infallible and they certainly aren't perfect.

Since also this mentioned 4k video, there's a good likelihood that these drives in those cases would be heavily written to in their lifespan.

probably more than you, in data centers, in raid systems and doing longevity studies and analysis.

Otto.. being in the hundreds of terrabytes isn't that farfetched using them as transient 4k video storage or backups.

I backup on average around 1 PB per year.

I also have 3 SSD hard drives in my laptop as well.

In reply to:

photosen: I've had an SSD in mind for portable backup for some time, my one doubt is about SSDs for long term backup.

actually they aren't really more reliable for backups than spinning hard drives.

current laptop spinning hard drives are incredibly durable, and they don't have wear leveling issues.

On article The whole nine yards: Canon 35mm F1.4L II USM review (259 comments in total)
In reply to:

AD in KC: OK, somebody's got to play Devil's Advocate: Why did Canon put the focusing ring at the far end of the lens when they don't have to? no zoom ring in the way here. When I'm holding a camera securely/comfortably, my left hand is under the camera - the focusing ring ought to be near those fingers.

And yes I love Canon - I make my entire (meager) living using their stuff.

it's an AF lens with full time manual focus? they probably felt with the weight it would get nudged off AF too easily.

In reply to:

beavertown: Minor differences in image quality but huge differences in prices. The Sigma is the all round winner.

Except there's no distortion correction that does just that. Good grief...

Pincushion on a UWA is a bad idea, just like barrel would be on the longer focal...

For what should be obvious reasons.

You'd get a lens because it corrects better for ...correctable flaws and yet loses out in the uncorrectable areas, such as resolving.

Yeah..makes total sense.

rrccad: I still find it surprising that some of the flagship phone models don't have DNG raw output.

Especially considering it's available in camera API 2.0 in Android.

Not even just picking on Sony here, Motorola is the same.

if I recall wasn't it hardware dependent on if the camera could support camera API 2.0? or was it simply firmware "hal" implementation?

In reply to:

brycesteiner: How come Nikon, Canon get all the lens coverage but Olympus, Panasonic and Sony are pretty much excluded from the DXO comparison chart? There are a couple but nothing that you can truly compare with these other brands to find out which system has the best lenses.

well, pretty simple math.

even now, canon and nikon are around 70% of the ILC industry.

if you factor in mount installed base, it's probably even larger.

so it'd be hard for Canon and Nikon to not receive the majority of the reviews,etc on a priority bases.

I guess it's like lossless raw compression then according to Sony ;)

and I stand corrected. the Moto Z can save DNG. well damn Lars, you just complicated my decision making.. even though I do think the LG G5 and UWA just makes so much sense. but being able to customize and build your own Moto is just way too cool.

edit again.. it seems to be a little more complicated .. moto z play does mot have DNG. without getting the hassy addon. the moto z .. doesn't say .. could you check please? :P

I think Sony's the last holdout then for RAW?

QuarryCat: So bad - Sigma failed again.
We all want the best Performance for half the price.
But all Nikon-Users will have to pay for the 14-24 mm monster or stay with the 16-35 mm VR -
all Canon-Users will dream from the heavy-fat 11-24 mm L or live with the very good 4/16-35 mm L IS
all others still wait for a real good ultra-wideangle or use single focal lenses.
The Tamron 15-30 mm doesn't deliver, not for Pentax, nor for Canon or Nikon.
And the new Sigma stays disappointing for to much money.
Next chance is Nikon, to built a real good, not so large 4.0/14-24 mm.

tbh the 24-105 art wasn't that special.
